Dear aromacloud,

I do think you need to update the admissions committee of your recent promotion--congratulations! If you have not spoken to anyone at the school yet regarding your application, it might be worth a call to try and get feedback on what concern(s) the committee has on your application, if any, so you know what to address in a letter. If the school has specified that you not contact the admissions office though, then don't--ignoring directions will reflect poorly on you.

Depending on what you find out, another recommendation might also be helpful. It is hard to really say whom you should choose as I don't know what you already submitted in your application, but I don't think a boss from your 3rd job is a good choice. You have not worked together long and he/she probably does not know you as well as the other two choices. If you feel that you need another perspective on your professional abilities and success, then go with your boss from your first job. If you feel you did not highlight your NPO enough in your application, then go with the co-founder (be sure to have him/her highlight your contribution, leadership, teamwork there). Other than that, I think it is a matter of waiting for the admissions committee to make determinations on the folks on the waitlist and hope that you stand out.

Best of luck,
Lisa

How would a good recommendation letter from the first boss make you look bad relative to your other jobs? The letter generally will address the recommender's perception of you in a professional capacity and examples of you from when you worked together, so it should not include any references to other experiences. If you feel this boss from your first job can add a valuable perspective on your leadership skills, then it sounds like he/she might be the one to ask.

Good luck,
Lisa
